To create an object, click on the desired tool, then move the pointer to the location where you want
one corner (or end of a line) of the object be positioned, then click
and drag to the location where you want the opposite corner to be placed,
then release. The newly created object appears with handles indicating
that it is active.

To change the object settings, choose the Object Info option
from the Object menu. The Object Info panel appears on the bottom of the
window. Alternatively, you may also use the click sequences to display
the Object Info panel:

- Control key + double click the rectangle and oval objects

The rectangular and oval objects can be switched to the text insertion mode
by double clicking on them (see Adding Text).
